Energy and exergy analyses were carried out for a pilot parabolic solar dish-Stirling System. The system was set up at a site at Kerman City, located in a sunny desert area of Iran. Variations in energy and exergy efficiency were considered during the daytime hours of the average day of each month in a year. A maximum collector energy efficiency and total energy efficiency of 54% and 12.2%, res...

Reactive power has been proposed as a method of voltage control for distribution networks, providing a means of increasing the amount of energy transferred from distributed generators to the bulk transmission network. The value of reactive power can therefore be measured according to an increase in transferred energy, where the transferred energy is defined as the total generated energy, less t...

Estimation of the power/energy losses constitutes an important tool for an efficient planning and operation of electric distribution systems, especially in a free energy market environment. For further development of plans of energy loss reduction and for determination of the implementation priorities of different measures and investment projects, analysis of the nature and reasons of losses in...

Sputtering Yields and Specific Energy-Losses of Noble Gas-Ions of 5.6 keV at Si02 Glass Sputtering yields and damage depths caused in Si02 glass and thin Si0 2 glass-layers by Ne-, Ar-, and Xe-ions of 5.6 keV are reported for the angles of incidence 0° , 45° , and 65°. Nuclear specific energy losses are derived from the mean damage depths. The results are compared with the theory of Brandt and ...

The deposition of x-ray energy resulting from the microexplosion i.o an inertial confinement fusion reactor and the subsequent thermal response of candidate wall coating and structural materials is examined. Evaporation losses and resulting melt layer thicknesses for these materials exposed to a variety of different x-ray energies and spectra are calculated. Softer x-ray energy spectra absorbed...

wheat is one of the important food staff in consumption pattern of each country. more than 50 % of human energy is supplied from bread in the developing country. combine losses is less than 2-3% in developed countries, while in developing country is about 15-20% in different regions and circumstances of harvesting seasons and field conditions. in this research project that effect of combine typ...
